Abstract
The utility model relates to a sealing ring, in particular to a new sealing rubber gasket used in double-wall corrugated pipe connection. A semi-circle sealing circle is respectively added on the upper surface and the lower surface of the normal O shaped sealing ring. A sealing lip is added on the lateral side of the normal O shape sealing ring. The rubber gasket is sealedly connected with a sleeve through the sealing lip. The rubber gasket is sealedly connected with the corrugated pipe through the sealing circle. The sealing effect of the utility model is greatly superior to that of the normal O shape sealing ring.
Description
Technical field
The utility model relates to a kind of seal ring, in particular for the novel seal cushion rubber of double-wall corrugated pipe connection.
Technical background
The Placement of plastic double-walled corrugated pipe adopts the socket joint sealed type to connect more.The socket joint sealed type connects the form that adopts an end enlarging, and the middle O-ring seal that adopts seals, and this Placement is easy and simple to handle, and is economical and practical, is circular but the conventional seals cushion rubber all is the cross section, and it is unreliable to seal.
Summary of the invention
The purpose of this utility model provides the novel seal cushion rubber of a kind of reliable performance, good sealing effect.
For achieving the above object, the utility model adopts following technological scheme:
Novel seal cushion rubber described in the utility model comprises the circle body of annular, and it is characterized in that: it is semicircular O-ring that the upper and lower surface of circle body respectively has a cross section, and the outside of circle body has the sealing lip of projection.
The sectional shape of circle body is trapezoidal, and both the thickness in the circle body outside was greater than the thickness of inboard.
The top of sealing lip is to lopsidedness.
The utility model is set up O-ring in the upper and lower surface of seal ring coil, simultaneously set up sealing lip at the outer surface of circle body, by the be connected sealing of sealing lip realization cushion rubber with sleeve, by the be connected sealing of O-ring realization cushion rubber with bellows, sealing effect is better than common O RunddichtringO greatly.
Description of drawings
Fig. 1 is an an embodiment's of the present utility model schematic cross-section;
Fig. 2 is another an embodiment's of the present utility model schematic cross-section;
Fig. 3 is used for the structural representation that double-wall corrugated pipe connects.
Embodiment
As shown in Figure 1, novel seal cushion rubber described in the utility model, the cross section of circle body 3 is trapezoidal, the thickness in the outside is greater than the thickness of inboard, upper and lower surface at circle body 3 respectively has a semicircular O-ring 2, and the outside of circle body 3 has the sealing lip 1 of projection, and the top of sealing lip 1 is to lopsidedness.
As shown in Figure 2, novel seal cushion rubber described in the utility model, the cross section of circle body 3 is a rectangle, the thickness in the outside is greater than the thickness of inboard, upper and lower surface at circle body 3 respectively has a semicircular O-ring 2, and the outside of circle body 3 has the sealing lip 1 of projection, and the top of sealing lip 1 is to lopsidedness.
As shown in Figure 3, when this novel seal cushion rubber was used for the double-wall corrugated pipe connection, by the be connected sealing of sealing lip 1 realization cushion rubber with sleeve 4, by the be connected sealing of O-ring 2 realization cushion rubbers with bellows 5, sealing effect was better than common O RunddichtringO greatly.
